I do. can see them in this pic:

I just bought polycarb sheet off ebay and made them myself. Rears are just held in the stock seals just like the glass. Fronts are bolted to the lip on the top of the door with rubber strip glued over to look a bit neater. I've not done the boot window but will do at some point. At the moment I need to lose some weight at the front end rather than more at the rear.

fibre glass bonnet then haysey...
how much did you give for the material and also is it anything special (flexiglass type thing) or just standard stuff?
-
yeah fibreglass bonnet, moving battery to boot etc...
the material is polycarbonate. Although to be honest, the rear windows are made from nylon or something like that but they are pretty crap, scratch too easily. Polycarbonate is what you want it doesn't go yellow with age and is more scratch resistant.
-
Yeah it seems that some materials are miles better than others. I just wondered whether there was a cheaper solution to buying the expensive stuff. I'll have a look into it when the time comes!
-
the polycarbonate I bought off ebay was pretty cheap, miles cheaper than anywhere else I tried. Can't remember the sellers name though as it was too long ago. Just search for polycarbonate sheet on there. I told the guy what size pieces I wanted and he cut them to size before sending them.

i got a set for sale of polycarb windows with sliders on front ones
-
just side windows or do you have the rear one too?
-
Is the rear screen bonded on? I have a rear screen that I want to fit soon.
-
yes it's bonded in
-
cheers guys, will crack on with making some up.↲

Same boat as hayesey though, need to loose weight upfront, heaters, dash and wiring loom have been removed and f/g panels are a hatred for me
-
Plastics4Performance should still have my templates for 4mm windows, inc sliders to fit windows without the rubbers surrounds, if its any help.
If your losing your heaters btw, have a think about demisting options... mine was bad for it and looked at a little 12v heater to pipe some warm air onto the front windscreen.
-
RainEX/anti fog spray is pretty good. I ran my E30 through a winder with no heater just by shoving that stuff on the inide.
-
I'll have to give that stuff a try, mine is a bugger for steaming up inside when it's cold and/or rainy outside, even with the heater. Another thing to mention is that when it's sunny outside it gets a bit like a greenhouse in there and the sliders don't offer much ventilation really, although I really should get round to putting one in the passenger side too. So I use the blower on cold just to keep cool in there too.

How much did they charge for the fronts?
I am going to have to custom make the rears as I have a square back and not the conventional coupe like most g40's
Currently using some stuff I got from a motorbike shop that they treat the visors on helmets with to stop any misting and it works perfectly, smells a tad like wd40 and came in a little bottle

the rears are really easy to make to be honest. All you need to do is use the original glass as a template and cut the plastic to the same shape using a jigsaw, then fit the plastic using the original rubber seals in a similar fashion as to fitting glass ones (using string around the seal). You don't even have to get the edges dead neat because they are hidden inside the seal.
Just make sure you use proper poly-carbonate material and not something else as other similar materials are more prone to going yellow in the sun and scratching.
-
Any tips for removing the rear windows ?
-
start by unhooking the seal in the bottom corner from inside the car and then just work round pushing the window out, it'll just pop out.
-
If its similar to MK2 Golf's, just get someone to sit inside the car with their feet pressed against the window and get them to push.
Then you stand on the outside holding the window, will pop out really easily.
